- Light
- Bright, indirect light for 6 to 8 hours daily; avoid direct harsh sunlight to prevent leaf scorching.
- Water
- Keep the soil evenly moist but never waterlogged. Allow the top layer of soil to dry slightly between waterings. Reduce watering frequency during the winter dormancy period.
- Growth
- Perennial tropical evergreen with an upright clumping growth habit, reaching mature indoor heights of 1 to 2 feet with a similar spread, growing at a moderate rate.
Care instructions
Provide bright, indirect sunlight and maintain high humidity. Water when the top inch of soil is dry, using a well-draining, nutrient-rich potting mix. Feed lightly with a balanced liquid fertilizer during the active growing season.
